I tried this test case and it fails with the error EOF

:-

package main

import (
  "testing"
  "encoding/xml"
)

type Email struct {
  Where string `xml:",attr"`
  Addr  string
}

type Result struct {
  Email []Email
}

func Test_Update_2(t *testing.T) {
  result := new(Result)
  body := "<result> <email where='home'> <addr>gre@example.com</addr> </email>"
  err := xml.Unmarshal([]byte(body), &result)
  if err != nil {
    t.Error("xml.UnMarshal:", err)
  }
  t.Log("result:", result)
}
